Axle Dimensions

Hub Face and Spring Center Measurements on Standard Trailer Axle

There are multiple ways to measure the length of an axle beam, but the hub-face-to-hub-face and spring-center-to-spring-center lengths are the most accurate. Hub face (A) refers to the length of the axle measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle (when hubs are mounted on the beam).


The spring center (B) is the approximate width of your trailer. It is measured from the center of the spring seat on one side of the axle to the center of the seat on the other. This axle beam comes with the spring seats welded on.


If you are replacing your trailer's axle, you should be able to figure out which type you need by determining your trailer's capacity, the bolt pattern of your wheels, the brake type and the aforementioned lengths.


Note: Axle does not come fully assembled.


Pre-Greased Hubs

A trailer hub with the grease cap taken off shows greased bearings

The pre-greased hubs in this kit come with the bearings, races, and seals already installed, which makes for a faster install time and less mess to deal with. After you've put on the grease caps and lug nuts (included), you'll be ready to roll.


etrailer Axles

etrailer axles are made of high-strength steel and come with spindles and spring seats welded on. The spring seats are attached to the underside of the axle so that the leaf springs (sold separately) can mount beneath the axle. The result of this underslung design is a trailer that rides a bit lower for quick and easy loading and unloading.


Each axle is manufactured to create a certain camber angle. This ensures that the angle of the wheels is correct for your towing needs. Because the primary concern when towing is maintaining controlled, in-line movement, each axle is made so that your trailer's tires will run along the pavement evenly, with contact across the width of the tread. The result is excellent straight-line acceleration for steady, in-line tracking. You might notice the bend near the center of the axle; this is what ensures the proper camber angle. Having the center ride a bit higher and the sides of the axle bent lower allows the axle to give just enough to compensate for the load.


Thoroughly Tested for Safety

This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI Laboratories for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.


Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern - Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Measuring To Choose The Right Trailer Axle

In order to find the correct replacement axle for your trailer there's a few things you need to do. The first one is we need to determine the capacity. The first place I always check for the axle capacity is on the axle tag, which is actually located on the axle. Now, most of these are in the center and they could be a white sticker or they could be a metal plate. Now, not all of them list the axle capacity, but the vast majority do, that's why I look here first. Granted, this is a new axle here, so the tag is in fairly good condition, but we can see on here GAWR, gross axle weight rating, 3,500 pounds, so I know this is a 3,500 pound axle.

So if you do have an axle tag and there isn't a capacity listed on there there may be a serial number, an axle number. And in which case, you could actually reach out to the actual manufacturer with this information and they should be able to give you the capacity. Some of the more common axle manufacturers on the market are Dexter and Lippert. So if you don't have an axle tag, that's okay. There is still other options to determine the capacity.

One would be to take a fabric tape measure and record the circumference of your axle tube. Now, once we have the circumference we can use the appropriate formula to get the diameter. And then using the diameter there's sort of a general axle guideline to determine capacity based on that diameter. So, for example, a 3,500 pound axle is gonna have a 2 3/8 inch diameter beam. Now, a 3 inch diameter beam would represent anywhere from a 5,200 pound to a 7,000 pound axle.

And there's also some larger ones as well as some smaller ones. So if we don't have that axle tag there we could just measure the diameter here of our axle tube. And another way is to actually look at the brake mounting flange bolts. Now, this is just gonna give you a rough ballpark. The 3,500 pound assemblies, they usually use this 4 bolt pattern where it's the larger 5200 to 7,000 pounds, use that 5 bolt pattern.

So that's more of a general guideline. That's certainly not all you wanna do, but it will help you reaffirm when you're measuring. So once we get to capacity there's two more things that we need to gather. The next one is going to be the hub face length. So the hub face length is gonna take our brake hubs into consideration. We're gonna be measuring from the part of the brake hub where our wheel mounts from one side to the other. So we'll go ahead and do that now. Now, once we have our hub face length, we need to determine our spring center length. So the spring center length is gonna be from the center of the leaf spring perch from one side to the other. So once we have all this information we can then use that to select the correct replacement axle for our trailer. We have a ton of different options to choose from based on a few different factors. Number one is the length of our axle, both the hub face and the spring center. There's gonna be several different options for each of these. There's also gonna be different axle capacities based on how heavy you need your trailer axle to be and how heavy your trailer is. Now, we always recommend replacing what's on your trailer with the exact same one that came off. So, for example, if your old axle had an 89 inch hub face that's what we'd recommend replacing it with. And the same goes for the weight capacity, although you can upgrade. No matter what capacity you need we should still have an option for you. Now, in addition to the capacity, we're also gonna have axles with a built-in drop if you need that, or just a straight axle. And we also have some different kits that are gonna come with some different components. We can either purchase the axle, just the spindle only axle. We could get this with an idler hub, or we could get this with an electric brake drum and some electric brakes, depending on what capacity you need..

I was worried about ordering trailer parts from a new company online. Product showed up fast and on time. Beat most other product pricing. A courtesy email was sent when product was delivered, making sure I was satisfied, giving me a direct contact incase I had any issues.
I haven't used the product yet but everything looks good.
Will order trailer product again in the future.

Exactly what I ordered packaged nice and pregreased bearings.



by:

Great value. I upgraded a 3500lb trailer and with the added brake it really helps. I use it to haul tools around so it handles the weight much better. Towing is a breeze now. Installation was easy as well. I will be buying more axles and parts in the future.



by:

Aside from not received complete order the first time, I will still recommend etrailer for all your needs



by:

Everything was going great on my new axle install today, until it wasn't. You shiped me the wrong lock washers for the brake backing plate. The correct nuts but the washers are to small. I'll have to pick them up because the customer is expecting the with to be done be today.



by:

The axle seems good. Nice that the ball bearings were grease. We will see over the miles if all goes well. The delivery, besides the break assembly was quick. Not sure why the break assembly was not shipped with the rest.



by:

Best thing I did was change axles to these. Went from 3500lb to these 7000lb with brakes on both. Tows and stops incredible.



by:

I wish I could give negative stars. My order arrived on time, but it was the wrong axle. The axle I ordered and paid for was a 3500 lb drop axle with electric brakes, they sent a bare 3500 lb drop axle. $[XX] difference. I immediately contacted customer service who required pictures of what I received. When I supplied them, they did not respond and even removed my order from their website so I can't track it to see if they're trying to make this right. They won't answer emails either because Ive sent a few. I'll try to get my credit card to refund me since they won't respond.



by:

Piece of cake to install. Pull out the old snapped axle install new axle. Bearings come pregreased.



by:

Wrong axle sent did not need the 4" drop down.



by:

I used these axles to upgrade my travel trailer suspension.they Seem to be a good quality item. Good paint job on the axles. Compared to axles that came with the travel trailer. Which helps living on the coast.



by:

The guys and gals at etrailer are the b est!



by:

Great product and customer service. Perfect replacement for my damaged axle. Would purchase from again.



by:

Not only is it not what I ordered 2 of the TA cayman parts and pieces in the advertisement. It doesn't say anything about coming in parts and pieces. I'm not a mechanic. Now I have to pay somebody to put it together. I think that's very poor business



by:

Paige was a huge help in getting me what I needed and fast!
Got my new axle in a day and was back on the road.
You will not be disappointed with etrailer!



by:

Product was exactly what I was after and helps me too get trailer back to work faster.



by:

Where the leaf spring sits on the axle was off about 1/4 inch had to finagle the axle abit but made it work.



by:

It's been a year since install and all is well! Thank you!

  • Replacement for 5-Lug Bolt Pattern, 89" Long Axle with 4" Drop and 74" Spring Centers
    Yes, if sounds like you're looking for the Trailer Axle with Idler Hubs # e72GR or Trailer Axle w/ Electric Brakes # e95SR for your application. These both match the hub-face and spring-center measurements you referenced, they have the 4" drop, and they also use the standard 5 on 4-1/2" bolt pattern you mentioned. Attached is an installation video of an axle for you to check out!

  • Option for Moving Spring Seat of 89 inch Trailer Axle
    We cannot move the spring seats here on our 89 inch axles like the # e95SR that you referenced and we only have options that are spaced 74 inches apart like this one. In order for you be able to use this axle you'd have to have new ones welded on like the part # TRSS238.

  • How to Determine Correct 7,000 lb Axle
    There isn't an axle kit, but for the correct 7,000 lb axle, you need to know the dimensions of your current axle's hub face to hub face and spring center to spring center; I have added a link below to a video which walks you through how to measure. For example, the Dexter Trailer Axle w/ Electric Brakes # 8327834-EB measures 95 inches hub face to hub face and 80 inches spring center to spring center. It also includes hubs with an 8 on 6-1/2" bolt pattern, so you'd need a wheel with that...

  • Replacement Parts Available for etrailer 3,500 lb Trailer Axle
    For the etrailer axle part # e95SR we do have replacement hub/drums with part # AKHD-545-35-EZ-K, and for brake assembly set # AKEBRK-35, for brake shoes # AKBRKR-S-10, and magnet # AKBRKR-M10.

  • Option to Replace 3,000 Axle With 4 Inch Drop
    We have an option but nothing in those measurements. The closest we have is the Timbren Axle-Less Suspension System, which are simply bolted or welded so you do not have to worry about finding an axle that meets any specific measurements. There isn't a 3,000 lb option but there is a 3,500 lb, and for that with a 4" drop, along with the hub and drum and electric brakes, you will need the following: - Timbren Heavy-Duty Axle-Less Trailer Suspension - 4" Drop Spindle # TASR35HDS03 - Trailer...
